Nice to see someone appreciating these great little cars. Still have my 1989 Gran finale which I bought new after the unfortunate demise of my Lancia Beta Coupe 1600. I ran a Janspeed exhaust for a while which sounded nice until it suffered early failure of internal baffles and no replacement was available.
I would love a little x19. Glad you get yours out and about on the road. Have you thought about doing a Euro bumper conversion? You were talking about the lines of the car in your video, and I think the disproportionate American bumpers they put on really hide the pretty lines of the x19.
